WebThe spectrophotometer is an optical instrument for measuring the intensity of light relative to wavelength. Electromagnetic energy, collected from the sample, enters the device through the aperture (yellow line) and is separated into its component wavelengths by the holographic grating. WebMar 29, 2024 · How Does a Microplate Reader Work? A microplate reader is a spectrophotometer that uses a limited range of wavelengths. Microplate readers shine a light source through a filter or a monochromator, …

WebNanoDrop spectrophotometers work on the principle of ultraviolet-visible spectrum (UV-Vis) absorbance. Nucleic acids absorb light with a peak at 260 nm. Purified proteins absorb light at a peak of 280 nm, while peptides and proteins that lack tryptophan and tyrosine residues absorb at a peak of 205 nm. http://www.microspectra.com/technical-support/248-spectrophotometer-design the pound era
